SPECIFICATION' forming part of Letters Patent No. 363,122, dated May 17, 188'7.

Application filed January 26, 1887. Serial No. 225,579, (No model.)

To @ZZ whom, it may concern.-

Be it known that I, FRANK RICHARD DIM- ICK, a citizen of the United States, residing at Savona, in the county of Steuben and State of New York, have invented a new and useful Improvement in Stove-Pipe Fastenings, of which the following is a specitication.

The invention is an improvement in stovepi pcs7 the object being to make a chcap,simple, and effective connection between the sections of pipe. Thisobject is secured by making near the lower end of each section of pipe a circular indentation and near its upper edge a T-shaped indentation, the stem of the T extending to the upper edge of the section, so

that the circular indentation of one section can be inserted into the reversedTshaped indentation of the next lowersection and turned into the horizontal part thereof, thus securing the two sections together, as illustrated in the drawings and pointed out in the claim. It is preferable to have both indentations made on opposite sides of the sections, so that the latter may have opposite points of support, and not one point ot' support only.

In the drawings, Figure l represents a perspective view of a section of a stove-pipe, showing the circular or pointflikc indentation near one end and the reversed-T-sbaped indent-ation near the other end, the stem of the T extending into the upper edge of the section. Fig. 2 represents a central vertical secA tion of two such sections of stove-pipe connected together and having indentatons on opposite sides.

Referring to the drawings by letter, A designates a section of a stovelpipe, having near its lower edge the diametrically-opposite circular or point-like iudentations B B and at its opposite edge the 1cversed-T-shapcd indentations O O, also diamctrically opposite each other.

By inserting, as described, the circular indentation of one section of pipe A into the stems of the reverscd-T-shaped indentations of a lower section, A, until the said circular indentations reach the horizontal part of the T- shaped indentations, and then turning either way, the two sections will be locked together.

b b are circumferential beads near the ends u I am aware that stove-pipe sections have t been connected by making a bayonet slot near the end of one section and securing a pin within the meeting end of a second section to lock in said slot. This requires the cutting of the pipe, and, moreover, makes the joint too open, so that smoke may escape therefrom. Such construction I do not claim, as the purpose of my invention is achieved by simply indent-ing the sections in the proper manner to cause them to interlock, and when so interlocked the sections make a perfect joint.

Having described my invention, I claim- As an improvement in pi pe-joints, the comv bination of the two sections ofpipe, each provided at one end with diametrically-opposite circular indentations B B and near its other end with the diamctrically-opposite inverted- Tvshapcd indentations O C', the stem of each T being extended to the edge of the pipe, and the heads of the two Tshaped indentations being arranged at right angles to thelcngth of the pipe, the circular indentations at one end of one section of the pipe being adapted to ride in the stem ofthe T-shaped indentations at the meet-ing end of the other section of pipe, whereby when the sections of pipe are turned slightly the circular indentations will lock themselves in the heads of the T-shaped ind entations, as and for thepurpose described.-

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

FRANK RICHARD DIMIGK.
